HTC released a new teaser image for its upcoming event where the M7 smartphone is expected to be unveiled.

The picture is of a huge eye and it features great definition focusing directly into the iris. This could be hinting towards a device with a 1080p display or a camera capable of taking pictures at this high quality.

HTC's event will take place on Tuesday.

Another image leaked earlier this week that appears to be HTC's first official picture of the handset. The image was tweeted out by EvLeaks, who normally leaks out information on upcoming products.

The device in the picture bears a striking resemblance to the iPhone 5.

The HTC M7 was also recently spotted in the popular U.K. retailer Carphone Warehouse's inventory list. A screenshot of the inventory was released by Pocket Lint, where the smartphone is listed as HTC M7 black.

The handset is expected to be an extremely impressive device that features several industry firsts. HTC will also replace the One X with the M7, making it the new flagship device for the company.

These firsts include specs that rival and top away many of the handsets currently available in the market, such as a 4.7-inch display with a pixel density of 468 ppi and a 1920 x 1080 resolution, a second generation 1.7GHz quad-core processor, 2GB RAM, 32GB of internal flash storage, and LTE connectivity.

However, the 4.7-inch screen size is still just a rumor, as NDTV is reporting that the handset could end up with a 5-inch display when it is released. The device is expected to be full HD (1080p) like its predecessors, the DNA and Butterfly.

The camera on the M7 is said to have some major improvements from previous HTC devices. It will come with a 1080p 13-megapixel rear camera, and a 1080p front camera.
